以生长一致、有6片展开叶的威廉斯香蕉幼苗为试验材料,研究0(CK)、1、5、10μmol/L 4个浓度的冠菌素喷洒香蕉幼苗后对香蕉幼苗耐寒性的影响.结果表明,1～10μmol/L浓度范围的冠笛素对提高香蕉幼苗抗寒性的效果不明显,并且呈浓度越高反而效果越差的趋势.只有1μmol/L的冠菌素对提高香蕉幼苗的SOD总活性、可溶性糖含量和叶绿素含量,以及降低相对电导率和丙二醛含量具有一定的作用.其中对提高可溶性糖含量的效果最明显,但是没有提高POD活性的效应.

Banana plants of 'Williams hybrid' with 6 unfolded leaves and uniform growth were foliar sprayed with 4 levels (0,1,5 and 10 μmol/L) of concentrations of Coronatine,and their cold resistance was observed under low temperature. The results showed that the foliar spray of Coronatine to the banana plants at the concentrations from 1 μmol/L to 10 μmol/L did not improve their cold resistance obviously and that their cold resistance tended to be lower with the increase of the concentration. Only 1 μmol/L treatment showed some effect on the banana plants in improving total SOD total activity,soluble sugar content (the highest) and chlorophylls content,and lowering relative electricity conductivity and MDA content,and this treatment failed to enhance the POD activity of the banana plants.
